Document Summary

Write the equilibrium constant expression (kc) for each of the following reactions: a. ) At 700 oc, kc = 9. 30 x 10-8 for the reaction. 0. 0020 moles of each component are added to a 1. 0 l flask. = 0. 002 m , similarly for [h2] and [s2] = 0. 0020 m. Since qc > kc, the system is not at equilibrium, and in order to reestablish equilibrium is has to shift to the left, and thus more reactants will need to be created. At 25 c, kc = 3. 5 x 108 for the reaction. Kp = kc (rt)d n kp = 3. 5 108 (0. 082 298)-2 = 5. 86 105. D ngas = 2 (3+1) = -2. For each of the following questions, circle the correct answer. If the following reaction is at equilibrium, what would be the effect on the amount of product if the pressure in the container is decreased? (10 pts) Product decreases product increases no effect on the product b. )
